In the Wikipedia glossary, an orphan is defined as "an article with no links from other pages in the main article namespace". These pages can still be found by searching Wikipedia, but it is preferable that they can also be reachable by links from related pages; it is therefore helpful to add links from other suitable pages with similar or related information. De-orphaning articles is an important aspect of building the web.

More colloquially, editors also sometimes use "orphan" to refer to pages that do not have as many incoming links as they ought to, even if they do not meet the technical definition for orphan status.

There are several factors that can classify an article or other page as an orphan:

• Orphaned article: An article with no incoming links which meet the criteria for linking below.
• Isolated article: An article that cannot be reached via a series of links from the Main Page.
• Walled garden: A group of articles that link to each other, but have few or no links to them from other Wikipedia articles. In effect the entire group is orphaned. Theoretically, a walled garden could have numerous articles if they all link to each other but no others link to them.
• Orphaned project page: A project page (starting with "Wikipedia:") with few or no links from other project pages. Essays are the most likely to be orphaned.
• Orphaned image: An image not used in any article.

Orphaned articles, since they have no links to them from other pages, are difficult to find, and are most likely to be found only by searching, or by chance. Because of this, few people know they exist, and therefore, they receive less readership and improvement from those who would be able to improve them.

In particular, if the topic is more obscure, this may make it difficult for many to locate. If not for links to a page, the only way such an article can be found is by a person who knows the topic entering it into Wikipedia or doing a web search, browsing a category in which it is contained, looking at the edit history of a contributor to the page, or having it show up by chance as a random article.

An article is orphaned if no other articles link to it.

In Wikipedia's early days, editors added Template:Orphan to mark both orphaned articles and articles with relatively few incoming links. The use of the template has since been restricted. It is now recommended to only place the {{Orphan}} tag if the article has zero incoming links from other articles. The template is only shown temporarily, under certain circumstances. Adding this template to any article is not strictly necessary, and many editors prefer to add it only when they believe that the article should be linked from many others.

A single, relevant incoming link is sufficient to remove the tag. Three or more incoming links will help ensure the article is reachable by readers.^[1] Editors may also remove the tag from any article if they believe that de-orphaning is unlikely to be successful, or if they have attempted to provide incoming links. See § What if I can't de-orphan it? below for more information.

The following pages do not count as incoming links:

1. Disambiguation pages
2. Any article in mainspace that is linked only in a hatnote
3. Redirects and Soft redirects
       ...except that incoming links to the redirects do count
4. Discussion pages of articles
5. Wikipedia pages outside of article space

The following pages do count as incoming links:

1. Any article in mainspace except those specifically excluded above (This includes links only present in collapsed navboxes.)
2. List of... articles
3. Set indexes

Neither soft nor hard redirects should normally be tagged as orphans.

Disambiguation pages themselves often should be orphaned. The only mainspace pages that should link to them are other disambiguation pages, and articles with hatnote links to them (via templates such as {{Other uses}}). Please do not place the {{Orphan}} template on disambiguation pages. See also Wikipedia:Disambiguation § Links to disambiguation pages.

Pages containing the templates {{Surname}}, {{Given name}}, {{SIA}}, {{List of lists}}, and any other set indexes also should normally be orphaned, as incoming links should usually be amended to target one of the items listed. Please do not place the {{Orphan}} template on these pages either.

Some very long lists are split into multiple sub-articles. The sub-articles are not orphans as long as they are interlinked amongst each other and also linked to from the first article in the series. See WP:NCSPLITLIST.

See the section below titled § Articles that may be difficult to de-orphan.

• There are 122 months of orphan articles in the backlog (Category:Orphaned articles), with a count of 53,073 articles.

Check at New pages feed for the most recent Orphan articles, highlighted in Red. Within the "New pages feed", below "Showing" there is a "Set filters" option to filter articles. After ticking "Are orphaned", click on the Set filters button.

The backlog of orphaned articles can be found in the following places (in order of priority):

• Category:Orphaned articles from November 2024—This category holds the latest articles marked as orphans. There are 596 new orphans so far this month.
• Category:Orphaned articles from October 2024—This category also holds the previous month articles marked as orphans. There are 790 articles tagged.

• Category:Orphaned articles from March 2015—This category also holds the earliest articles marked as orphans. There are 5 articles tagged. Some editors believe it is important to tackle the oldest orphans first.

• Category:Orphaned articles from June 2024—This category contains the most amount of articles marked as orphans. There are 2,511 articles tagged. Some editors enjoy making progress on a challenge.
  • Category:Orphaned articles from August 2024—This category contains additional articles marked as orphans. There are 2,229 articles tagged. A contest for these two months.

• Category:All orphaned articles-This category holds all orphaned articles, de-orphan articles, and a Filter this category by topic section.
  • Category:Orphaned articles—To find orphans from other months and view the backlog.
  • Category:Attempted de-orphan—This category holds articles which someone has tried to de-orphan, but was unsuccessful. These can be saved for later in favor of orphans which have not yet been attempted.
• Wikipedia:Orphaned articles by WikiProject—This links to pages listing orphaned articles by subject.
• Special:LonelyPages—A page from Tools → Special pages → Orphaned Pages. This page updates irregularly and often isn't current, although it is easy to find.

• To verify if an article is currently an orphan, at the toolbox, click the "What links here" link (or shortcut Alt+⇧ Shift+j). If the article remains an orphan, continue below, otherwise remove the orphan tag. Note that articles years old in the backlog, or incorrectly tagged by AWB may no longer be orphans. The "What links here" shows any articles which mention the name or part of the name of the orphaned article. If the page lists other names or has redirects, consider searching for those terms as well.
• For the verified orphan article, at the toolbox, click on "Related changes" (or shortcut Alt+⇧ Shift+k), to see changes on pages linked to or from that page.
• Highly related articles are typically linked:
  • In the uppermost lead of an article
  • In a "See also" section (if existent)
  • At the automatically suggested "RELATED ARTICLES" below the article. Note that "Related articles" feature is supported in Minerva skin (and hence mobile) and in Timeless skin.
• Find related articles with intersecting categories using the PetScan tool, or reviewing various categories at the bottom of the article. See: Petscan documentation for help getting started.
• Sometimes, the highly related terms aren't yet wikilinked despite a Wikipedia article existing so it is often a good idea to do a Google search of related terms found this way. Furthermore, the article's categories might contain related articles as well.
• Consider using Edward Bett's Find Link Tool to search Wikipedia for linking opportunities.
• An effective way of finding related articles and sections is to search the Web for related terms and appending the word wiki or Wikipedia or site:Wikipedia.org to them.
• Biography articles often can be wikilinked into: place of birth or death (add into a "Notable people" section), or one of the many "List of xxxxx" lists.

If this doesn't help, then a little more research is required. First, read the article. Then, follow some related-looking outgoing links from the orphan to other articles, and do a Web-wide search for the article topic. Doing these will give you a much better idea of what it relates to. Not only will it probably give you information you can use to add meaningful links from other articles, but it will probably give you enough info to flesh out and improve the orphan itself. (This is, after all, the main purpose of Wikipedia.)

Be careful to check that the search results refer to the topic of this article, and not something else of the same name. When you find an appropriate parent, insert a meaningful link to the orphaned article. The link can be a meaningful new sentence added within the article, or consider using the {{Further}} template.

When adding a link to an orphaned article, please use this edit summary:

Adding link to orphaned article, Wikiproject Orphanage: [[Wikipedia:ORPHAN|You can help!]]

Once the article has one or more links that fit the criteria, remove the tag, if one is present. Make sure to update the edit summary to reflect the article has been de-orphaned.

• Check if the article's Talk page (or create if it does not exist) needs additional relevant WikiProjects. Doing so may attract attention from interested editors to help. The Rater tool makes adding wikiprojects easy to do.
• Check to see if there are articles about the same topic under a different name. If that is the case, it may be suitable to merge the orphaned page to the other, or vice versa. When the merge occurs, links from the other page may provide the de-orphaning.
• Consider creating reasonable redirects to the article. (Some alternative titles may already have links to them, or searching for the alternative titles may suggest other appropriate links.) Redirects do not technically count as "articles" in de-orphaning, but do provide more ways a page can be found. The redirect may also previously exist as a red link on another page, thereby providing some linkage.
• Place the article name in quotation marks and click search (if the article title is a single word, quotes are not needed). This will list all the articles containing the term. Examine each one, and determine if the term in these articles means the same as the orphaned article. If it does, add an internal link. If it does not, simply ignore it. The same word or phrase that is used in the title of an article may have multiple meanings.
• If any related articles have a See also section, it is worth considering if the orphaned article may be listed there. However don't just add links there indiscriminately! Adding links to See also could be considered a quick 'easy way out' to de-orphaning an article, and may attract the wrong kind of attention from other editors if poor-quality or only tangentially-related articles are 'dumped' into the See also section of an article they worked hard on. They may be of mind to revert you and even accuse you of mindless link-spamming. So always keep overall quality in mind.
• Check to see if there are any Lists or Indices of whatever subject the orphaned article is about, or disambiguation pages listing articles with similar titles. If it belongs, you can add it there (although disambiguation links do not count towards de-orphaning).
• Search categories in which the article is contained and other similar categories for related articles. It may be worth listing the orphaned page in a see also section, or even adding new [appropriate] text (even a minute amount) to one or more of these articles in order to provide a link. These may include adding a new heading with a {{Main}} tag below the heading and possibly a brief description.
• Identify one or more navboxes containing articles in a category common to the orphan. According to some editors, this is the very best way to de-orphan, for it provides dozens of instantaneous links if a navbox is available. To do this, find the navbox, and add the article where it best belongs. You can edit a navbox by either visiting its title (beginning with "template:") or navigating to a page containing it, and clicking the letter "e" at the top-left corner. Once you add the orphaned article to a navbox, add the navbox to that article. If no suitable navbox exists, and you have the skills to create one, you can create a new navbox for the orphan and other related articles.
  Note: While adding a navbox is very effective in increasing the number of links to a page, it is important to assure that at least some of the articles within the navbox have links from articles outside of that navbox; otherwise you are left with a walled garden.

For biography articles, there are several possible options:

• Look for the orphan article's place of birth (or death). Open that place article and look for "Notable people" section. If that section does not exist, add one. Then add the orphan article there. (Occasionally instead of "Notable people" the section title may be "Personalities", "Notable residents", etc.)
• Look for date of birth or death, then add the person to that article. Begin by searching Category:Year lists by country. Within that country, (List of years in Sweden for example) click on the year (example, 1980 in Sweden. Next, add a wikilink for the orphan article in the appropriate section (births, deaths, events).
• Within the Wikipedia search box, "People from..." or "List of people from" may be helpful to find a place to add the orphan article. Another example, List of Argentines where notable people can be added.

Some year articles exist or could be redirects. These are a few examples using the Wikipedia Search box:

• June 1937, article, with daily sections
• June 1993, Redirects to 1993 article, June Events section
• Births in 2008, Redirects to 2008 article, Births section
• Deaths in July 2008, article, with daily sections

The fact that an article is an orphan is in no way a reason for deletion. At worst, an orphan is just an article created by a less experienced editor who does not understand that it is important to provide sources, links or even categories, or by a more experienced editor who simply cannot find any other pages that can link to the subject. Or it may be a relatively new article that the creator is planning to link from other pages, but has not identified other articles or otherwise carried out that task yet (a page generally should not be tagged as an orphan until it has been around for a little while). Being an orphan is not a reason to delete an article, only to fix whatever issues it has.

An orphan, especially if it has been created by a newbie, may need to be flagged with other article issue tags. See {{Multiple issues}} for a list of issues with which an article can be flagged.

It may be the case that some articles currently just cannot be de-orphaned. If this is the case then please do not try to 'force-fit' by adding unrelated links to articles where they don't belong just for the sake of de-orphaning. Always keep in mind that our primary goal is to improve the reader's experience, not satisfy the editor's indulgence in statistical achievements. Your priority when adding links should be to maintain article quality by adding relevant and useful links wherever possible.

Take a look on the article's talk page and see if there is a WikiProject message box. If not, add an appropriate WikiProject template. More than one message box can be added if needed. This should bring the article to the attention of subject contributors who may be able to help de-orphan.

For Talk page of orphan articles, add the following notice to increase the orphan visibility.

{{Notice|{{see also|Wikipedia:Orphan|Wikipedia:WikiProject Orphanage}}}}

When adding a notice to the talk page, please use this edit summary:

Some orphaned articles may not meet Wikipedia's notability guidelines. If a thorough search for significant coverage in reliable sources is unsuccessful, appropriate action may include tagging the page with {{Notability}}, a proposed deletion or deletion nomination.

When you do encounter an article that you are unable to de-orphan, but still feel that it is possible to be de-orphaned, then add the date you tried to de-orphan it to the orphan tag using the att parameter. The "att" is an abbreviation for "attempt", as in "I attempted to de-orphan this article but failed". The rationale is that although you were unable to de-orphan the article, it is often the case that someone else may be successful. However, if you are certain the article is unlikely to ever be de-orphaned then simply remove the tag.

To use "att", update the {{Orphan}} tag with: |{{subst:ATT}}. If there are already other cleanup tags and they're within the {{Multiple issues}} template no special considerations are generally required.

There are several benefits of using the de-orphan attempt (att) parameter. It is a placemarker for those trying to do initial de-orphaning (i.e., indicates that somebody tried it and when). Also, articles where de-orphaning was tried quite some time ago may be easier now (many articles become easier to de-orphan once more articles in related areas have been filled in). You can be sure you won't end up looking at the same orphaned article twice because once it's tagged with |att=November 2024 it gets removed from the category it's currently in (Category:Orphaned articles from November 2024) and gets placed into the attempted de-orphaned articles category (Category:Attempted de-orphan from November 2024). This category may be a place for those de-orphaners who want an extra challenge. Remember that only a single incoming link is required in order to completely remove the orphan tag, but any additional links will certainly help ensure the article is not isolated, so the attempted de-orphans category may also be a place to hold those articles where you feel there is potential for more incoming links.

Also, when placing the |att= parameter, it's unnecessary to remove the pre-existing |date= parameter, as they are two separate and distinct parameters that complement each other. Instead of replacing |date= with |att= simply place it in addition to it. This gives editors the added benefit of knowing when the orphan tag was first placed on the article. Note that this does not double-categorize it, the |att= takes precedence and, as was mentioned above, the article is moved to the attempted de-orphan category for that date, so you're not having to revisit the same article twice when browsing through the monthly orphaned articles category. However, the all-inclusive Category:All orphaned articles still remains regardless; this is deliberate and is needed to categorize the article as still being an orphan.

Attempted to de-orphan. Wikiproject Orphanage: [[Wikipedia:ORPHAN|You can help!]]

• Organisms/Taxonomic/Species articles: Unless they're part of a navbox, it's highly unlikely that these specialized subjects will be linked to from more than one other article (although note that this has no bearing on their notability). Given that there's such a huge number of these and that many of them are one- or two-line stubs, it does not help to improve Wikipedia by tagging every single one with an orphan tag, and in fact may be seen as disruptive by other users. Please focus on the ones where there's at least a chance of inter-wikilinking.
• ... in popular culture, List of works by ...: Usually the only article that will ever link to these will be the "parent" page about the subject itself. Obviously it's not necessary to get multiple links for these. There are many other cases similar to this (ex. "Lists of ..." lists, "Index of ...", "Glossary of ..." etc.) and other navigational types of articles, where just using a little common sense goes a long way in ensuring Wikipedia remains an enjoyable experience for the reader as well as the editor.
• Surname pages: These are a special case, some may be among those types of articles known as "set index" articles, whilst others are encyclopedic articles related to anthroponymy that may be easier to de-orphan. If it's possible to de-orphan these, great. If not, just remove the tag if it's there and don't worry about it.

Although a bot or script is capable of regularly checking articles to see if they are orphaned, you can help too manually. When reading an article, you can check what other pages link to it by clicking "What links here" in the toolbox, or shortcut Alt+⇧ Shift+j. You will then be provided with a list of pages that link to that article. If it meets the criteria, and you don't have the time or knowledge to de-orphan it right away, you can add the {{Orphan}} template to the top of the page (after "Short description" line), marking it as an orphan. If you use AWB when tagging, be sure to read the page "AWB and orphans". Note that WP:AWB has a feature to tag/untag articles with orphan tags. If set incorrectly, AWB can falsely tag articles not orphans, as well as remove an orphan tag that should remain.

When creating a new article, it is best to prevent them from being orphans from the beginning. Advice can be found at Wikipedia:Drawing attention to new pages. Finding possible links may be time-consuming. Don't worry if you cannot make all the necessary edits on the same day, as long as you keep your plans in mind!

There are presently a lot of orphaned essays. An essay is defined as "orphaned" if none of the following types of pages link to it:

• Other essays
• Policy and guideline pages
• Help pages

Deletion discussions, talk pages in any namespace, lists and directories in project space, and subpages do not count toward meeting the minimum.

An orphaned essay is much harder to find than an orphaned article because there are fewer alternative methods available than there are for articles.

An essay that is orphaned should be marked with the template {{Orphaned essay}} immediately below the {{Essay}} template. This will automatically place the essay in the category Orphaned Wikipedia essays.

The {{Orphaned essay}} tag and the criteria used for orphaned essays are completely separate from orphaned articles. Although the guidance on this page may still apply to orphaned essays, they should be considered less of a priority.
